Life-Runes are runes which were planned to be used for summoning spells. The idea was eventually scrapped. Summoning later returned as a skill with different mechanics in RuneScape 2. Life-Rune remains in the client, but all spells using it have been removed. In older clients, the spells were not visible on the normal magic interface or loaded, but existed in the data file "config", and could be made visible by editing the data file.
